1) Fuel Mileage for a car of this size (but then again, I have a TCH

)
2) Quality - haven't had any significant problems. I had the center console squeak, but I fixed that myself. You would expect to have some minor problems with a first-year model car, anyone expecting to have a "perfect" 07Camry is kidding themselves. I bet the 2008 model will have the various squeaks resolved. As long as I have no problems which I consider more than "annoying", I'll be happy with the quality.
3) Styling - the last generation Camry was BORING. I love the back-half of the 2007. The only part I could do without is the bubble nose. I think the SE looks awsome and I can't wait to get those ground effects to put on my TCH.
4) Audio - as someone else mentioned, this is the best factory stereo I've ever had in a car, and that includes my CaddySTS and Ford T-BirdSC both of which had powerful systems with subwoofers. While the MP3 and AUX are excellent features, they are pretty much standard with any stereo system nowadays. But the bluetooth is awsome, I love having a true hands-free cell phone without an annoying headset.
